How to populate an array automatic with an user` input?

Question

i m writing a code as homework, the task is to create a code, where the user give a number (for example 4 ) and the output will be all the number from 4 ( the users input ) till the length of array (10), the task is to do just with a for-Statement. literally i m trying as much i can, but every time the output will be 10 times "0", or the users will have to give as input 10 times the numbers. here what i wrote the last time before i asked here hel; i ve tried to look for others similar things here or on other sites, but i didn´ find soemthing related specificately to it... thank you

here the last tentative i ve tried

import java.util.Scanner;
import java.util.Arrays;

public class Arrayspopulate {
    public static void main(String[] args) {
        Scanner firstnumber = new Scanner(System.in);
        int [] array = new int [10];



        System.out.println(" Please give the first number");
        for (int i = 0; i < array.length; i++){
            array[i] = firstnumber.nextInt();
            System.out.println(array[i]);
            }
        }
        }

You need to take a single positive integer from the user, and populate the array with consecutive values starting from the value the user entered. Therefore, you have to iterate through all positions of the array and initialize them to a value that equals the current position of the array plus the value entered by the user:

import java.util.Scanner;
import java.util.Arrays;

public class ArraysPopulate {
    public static void main(String[] args) {
        Scanner firstNumber = new Scanner(System.in);
        int [] array = new int [10];
        int value = -1;
        while (value < 0) {
            System.out.println(" Please give the first number");
            value = firstNumber.nextInt();
        }    
        for (int i = 0; i < array.length; i++){
            array[i] = i + value;
        }
        System.out.println(Arrays.toString(array));
    }
}

Input: 4

Output: [4,5,6,7,8,9,10,11,12,13]

Asking the user for the size of the array and creating it to have that size is left as an exercise for the reader.
